1. A presentation on SMART DUST
Presented by:-

2. Smart Dust – An Introduction
Miniaturization
MEMS – Micro-electro-mechanical Systems.
Radio transmitters and receivers
Tiny Computerized Sensors
Single units known as MOTES

4. Smart Dust History
Conceived in 1998 by Dr. Kris Pister of University of California – Berkeley
Funded by DARPA – Defense Advanced Research Project Agency
Powering Issue

5. Smart Dust Overview
Merger of Computers, Mechanics and electrics with miniaturization technology
Its core is small, low power Computer
This Computer monitors the sensors embedded in the same chip
Uses RF link for communicating and transmitting necessary information along with MEMS embedded in the same chip

6. Components & Specifications
A small, low power computer, with a operating system called Tiny OS.
Sensors
Battery
Reflectors and transmitters for reflecting the laser beams
And other as per requirements of the dust

9. Smart Dust Working Motes are run by Microcontrollers
Microcontrollers takes the reading from the sensors, processes it and stores it
It uses optical receiver to receive the messages from other motes
It uses corner cube retro reflector or “Laser” to transmit sensor data to other motes

10. Smart Dust working
The batteries are the basic powering devices in the motes
The motes are in sleep mode most of the time with a little consumption of a few micro amps
Counters and timers periodically trigger on the sensors which take the readings, micro-controller transmits them, stores them and the mode again goes to the sleep mode

11. Applications Military Smart Office Spaces Environmental Applications
Diagnosis of Human Problems
Security Purposes
Conservation of resources
And many more………………..

12. Smart Military Operations
Can be used to sense enemy movements
They can help to collect battlefield intelligence
Can be proved as a weapon against bioterrorism
Can be proved as brilliant spies

13. Smart Environment Can be used as seismic sensors
Can be sewn in clothes to sense the working environment and change in it, so that the user can get better off it
Can be used to identify the pollutants present in the environment
Can make our life better by sensing these elements

14. Smart Medication Can assist a Handicap person about the paths
Can assist in detecting and destroying tumor cells in the body
Can help to identify Various type of diseases for whom the definitions are not yet given by defining them in the tiny OS and matching them

15. AD-HOC networks
Smart dust can be used to form Ad-hoc networks, which can use radio link to transmit data
These ad-hoc networks can be used in various fields where normal links are not possible
Ad- hoc networks can be much cheaper than usual modes of certain applications

16. Future Goal
In march 2003, this mote named Spec was made in which all the contents of a mote were fitted in less than 5 Sq mm, in less than a dollar. We can imagine motes to be as small as Dust Particles.

17. Future Goals Weather/seismological monitoring
Internal spacecraft monitoring
Land/space comm. networks
Chemical/biological sensors
Weapons stockpile monitoring
Defense-related sensor networks

18. Conclusion Smart dust is the power of pc in a dust particle.
Extent of miniaturization
Can help us to lead a better life, in our own beautiful environment

19. Any Questions???
